corrected remux.c

line 533
case SI::AC3DescriptorTag:
+case SI::EnhancedAC3DescriptorTag:


and in line 191:

-Target[i++] = SI::AC3DescriptorTag;
+Target[i++] = SI::EnhancedAC3DescriptorTag;

I attached a second version of the first patch. 
I make the same changes that in the second patch, but maintaining the logic of 
the first patch. Also I commented the line:
+//        this->context->request_channels = 2;
because your example has 5 channels. If you have trouble with that you can 
comment the line again.
Which  typo error has the second patch?

i 've patched pat.c and now remux.c
and with use xine-lib-1.2 with your second patch (who has typo error)
and that doesn't work.

corrected remux.c

with your previously patch and just pat.c patched with
line 402

case SI::AC3DescriptorTag:
+case SI:EnhancedAC3DescriptorTag:

that worked but not stable.

Is your sample eac3 has |"Spectral extension" ?
because in france dvb-t with eac3 has it
and need a ffmpeg patched for that.
And i test with that sound.

It works here with a old sample of tdt with eac3. Have you patch also
remux.c? You need to change in line 533:

case SI::AC3DescriptorTag:
+case SI:EnhancedAC3DescriptorTag:

and in line 191:

-Target[i++] = SI::AC3DescriptorTag;
+Target[i++] = SI::EnhancedAC3DescriptorTag

Hi

I have made previous test with the version release by Petri Hintukainen

And I notice this part is not working like it should

-    if((m->descriptor_tag == STREAM_AUDIO_AC3) ||    /* ac3 - raw */
+    if(m->descriptor_tag == HDMV_AUDIO_84_EAC3) {
+      m->content   = p;
+      m->size = packet_len;
+      m->type |= BUF_AUDIO_EAC3;
+      return 1;
+
+    } else if((m->descriptor_tag == STREAM_AUDIO_AC3) ||    /* ac3 -
raw */

unfortunaletly, in AC3 or E-AC3 , the descriptor tag is
STREAM_AUDIO_AC3, so the program never run the first if (installed a
debug printf here)

It seems that your first approach (at least what I understood) by
forcing the decoding of all AC-3 stream by ffmepg instead of internal
lib was nice but generate violent segfault on libavcodec

Hope this help you

Best regards
